Dust collecting attachment for electric power tool and electric power tool
A dust collecting attachment that is mounted on a sander includes a suction portion mounted on a portion of a front housing where an output shaft projects, a flexible hose having a front end of the flexible hose connected to the suction portion, a discharge portion connected to a rear end of the flexible hose and a changeable member placed on both a motor housing and the discharge portion. The changeable member allows the discharge portion to be mounted at any position around an axis of the motor housing.
1. A dust collecting attachment for an electric power tool, which is mounted on the electric power tool that has a housing extending in a longitudinal direction and used as a holding portion, and an output shaft projecting downward from a front part of the housing, comprising:
a suction portion mounted on a portion of the housing where the output shaft projects;
a pipe having a front end of the pipe connected to the suction portion;
a discharge portion connected to a rear end of the pipe; and
a changeable member that is placed on both the housing and the discharge portion, and allows the discharge portion to be mounted at laterally symmetrical positions with respect to the housing, wherein
the pipe is divided into a plurality of divided pipes detached from each other and reconnected together in laterally reversed orientation, and by selecting lateral orientation of the divided pipes, the pipe can connect the suction portion and the discharge portion on a lateral surface side of the housing which corresponds to a lateral position of the discharge portion.
2. The dust collecting attachment for an electric power tool according to claim 1 , wherein
the pipe is formed so that at least a portion of the pipe along a lateral surface of the housing has a flat transverse section conforming to the lateral surface of the housing.
3. The dust collecting attachment for an electric power tool according to claim 1 , wherein
the divided pipes are connected by insertion, a protrusion is formed in one of an inserted end and a receiving end of the divided pipes, and a through hole or a recess is formed in the other end so that the protrusion fits in the through hole or the recess when both of the ends are connected by insertion.
4. The dust collecting attachment for an electric power tool according to claim 1 , wherein
the pipe is formed by connecting four divided pipes, which are first to fourth divided pipes.
5. An electric power tool, comprising:
a housing extending in a longitudinal direction and used as a holding portion;
an output shaft projecting downward from a front part of the housing; and
the dust collecting attachment for the electric power tool according to claim 1 .
